Visual context processing and its development in gamers and non-gamers

Visual context processing was investigated in both action video game players and nonplayers using the Ebbinghaus illusion task (N = 312, 39.4% female) in a cross-sectional study design. When presented in context, players showed markedly poorer target size discrimination accuracy compared with nonplayers in the 6-, 7-, 8-, and 9-years old age groups, but this difference was reduced in 10-years old group and diminished in adults. When presented in isolation (no-context), the two groups displayed similar performance in all age groups. Furthermore, nonplayers (linear) and players (bell curve) showed profoundly different age-related differences in context processing. These findings provide evidence that players might have enhanced perceptual bias to process visual context in the transition from early childhood to early adolescence, and the differences between the two groups start at early ages and continue with distinct developmental profiles.     

跨期选择的变易程度正向预测中华文化圈国民的自评扛疫成效：亚非欧美大洋洲18国跨国研究

跨期选择是对不同时间点的得失的权衡与选择。伊索寓言《蚂蚁和蚱蜢》假借群居型昆虫的跨期选择偏爱暗喻投资未来的慢策略比只顾眼前的快策略更利于生存。用跨期选择领域通用的语言解读这一寓言便是：选择大而迟选项的蚂蚁比选择小而早选项的蚱蜢更可能扛过严冬而生存下来。为了探索何种跨期选择策略更有助于我们扛过疫情,本研究调查了亚非欧美大洋洲这5大洲18个国家共计26355名受测者对混合得失双结果的跨期选择偏爱,测量了人们平时和疫时跨期选择偏爱的变易程度(2类变易的程度指标),以及人们自评的扛疫成效。跨文化比较结果的主要发现是：不同通货的选择变易程度(指标1)和不同时期的选择变易程度(指标2)能联合预测中国/新加坡文化圈国民的自评扛疫成效;不同时期的选择变易程度(指标2)也可以单独预测印度/马来西亚/菲律宾/尼日利亚文化圈国民的自评扛疫成效;这2类选择偏爱变易的程度指标不能预测其他文化圈国民的自评扛疫成效(或者预测方向和假设相反)。基于易经“穷则变,变则通”的要旨和跨国比较的发现,我们认为：面临历史危机时善于变通的特长抑或成就了中华民族特有的竞争优势;在应对危机时,与中国文化距离越相近的国家或民族抑或也能...     

“‘WE' AND ‘THEY'”: WHY MUST WE ENGAGE IN CROSS-CULTURAL CONVERSATION?

This article contains the principal ideas that I presented in four different sessions at the IRAS 2022 conference, on the theme “‘We' and ‘They’: Cross-Cultural Conversation on Identity.” Focusing on the central topic, the article begins with (i) the contents of my opening lecture; followed by (ii) a broad outline of the concerns discussed in my book, Cross-Cultural Conversation: A New Way of Learning, intertwined with glimpses of the intellectual journey that led me to CCC, delivered in the Book-discussion session; (iii) a summary of the main ideas about the importance of meeting of religions today, which formed the background for the CCC Panel discussion on religion, where I was in conversation with spokespersons of five world religions; and (iv) my comments on how science–religion dialogue can help promote a sense for human solidarity by combining knowledge with wisdom, in the concluding session.     

Prosocial orientation and COVID-19 vaccine willingness in the U.S.

Despite evidence of the safety and effectiveness of COVID-19 vaccines and their wide availability, many in the U.S. are not vaccinated. Research demonstrates that prosocial orientations predict COVID-19 health behaviors (e.g., social distancing) and vaccination intentions, however, little work has examined COVID-19 vaccination willingness in the U.S. since vaccines were approved. Findings from two U.S. samples show that, in contrast to other COVID-19 health behaviors, vaccine willingness in unvaccinated people is unrelated to prosocial orientation. Study 2 demonstrates that the lack of association between vaccine willingness and prosocial orientation in unvaccinated participants was specific to those with stronger beliefs that COVID-19 vaccines are ineffective. Thus, in prosocial people, perceptions of vaccines' ineffectiveness may undermine COVID-19 vaccine willingness.     

Behavioral case formulation: An experimental assessment study of transient tic disorder

A nine-year-old male, who met DSM III-R criteria for transient tic disorder, participated in an experimental assessment strategy to generate support for a case formulation. In addition to presenting motor disturbance, assessment procedures revealed six problem areas. All problems were formulated as manifestations of a hypersensitivity to evaluation, etiologically related to the boy's relationship with an insecure and critical father. It was hypothesized that the patient's tic disorder was a consequence of his hypersensitivity to father's excessive criticism, which then generalized to other evaluative situations. Using a controlled single-subject design, predictions derived from the formulation were tested by exposing the child to a planned combination of evaluative observers (e.g., father, mother, therapist, etc.) who watched him as he worked on a series of puzzles. The dependent measures included (1) behavioral recordings of tic frequency and (2) frontalis EMG responses. The results indicated significant differences in tic rate and EMG as a function of the type of observer. Consistent with the formulation, the patient displayed the highest levels of tic behavior and EMG response when his father was the observer and lowest in the presence of the mother. Predictions regarding other stimulus conditions were also confirmed. These results provided support for the case formulation that was used to design an effective treatment intervention. Findings suggest that the case formulation model offers a method whereby novel case hypotheses can be generated for poorly understood psychopathology and tested later in the experimental situation.     

Empirical research on the identification of singular,multiple and subordinate argumentation

To examine to what degree argumentation skills are mastered by pupils who attend the vocational, general and academic streams in Dutch secondary education various subtests were constructed. The theoretical study of argumentation as exposed by Van Eemeren and Grootendorst was the basis for this test construction. In this article tests for the identification of singular, multiple and subordinate argumentation are described. Also an account is given of a pretest of these three subtests.     

Neuropsychological identification of motor problems: Can we learn something from the feet and legs that hands and arms will not tell us?

The degree of structural and functional specialization that differentiates between upper and lower limb use in humans is quite unparalleled among primates. It is argued that less neural resources are devoted to leg and foot control than to arm and hand control, and that this aspect of lower limb innervation, together with the uniquely restricted use of the lower limb, renders lower limb function more sensitive to general neural insult. In addition, the status of leg and foot control differs from that of arm and hand control both early in life and during the later years of decline.     

Physicians,entrepreneurism and the problem of conflict of interest

This paper examines the ethical issues of conflict of interest raised by the burgeoning development of physician involvement in for-profit entrepreneurial activities outside their practice. After documenting the nature and extent of these activities, and their potential for conflicts of interest, the paper assesses the major arguments for and against physicians' referral of patients to facilities they own or in which they invest. The paper concludes that an outright ban on such activity seems ethically warranted.
